![]() ![]() Scale â you can grab on one of those corner grips and drag it to size the objects. Also while in this mode, you'll see a tri-wheel rotation thing appear in the 3D view which allows you to grab any one of 3 rotation axes easily there for spinning things around in different directions. You can use this if you want to rotate a rectangle around one of its own corners for example. If you click instead of drag on the rotation grip, it will switch to a different mode which makes it possible to grab the center rotation pivot and move it to whatever spot you would like. So for example if you want to rotate something by 30 degrees, type in <30 and push enter, then grab that rotation grip and it will move in 30 degree increments. There are 2 ways you can enter an angle constraint, either by typing <45) just by typing directly without clicking anywhere, or by clicking on the angle box in the bottom toolbar and entering your value there. If you want to rotate by a specific angle, you can do that by entering an angle constraint before (or during) dragging that rotate grip. Rotate â you can click and drag on the rotation grip located in the middle of the top edge of the bounding frame to do an immediate rotation. ![]() When you drag the grips, if you have grid snap turned on, then that new target point will snap on to the grid and you can snap on to any point you can normally snap on to when dragging that handle (the grip is actually slightly to the outside of the actual point that you place when you drag it).įor rotation it is using the same snap settings as you can currently use for drawing an angled line (Snaps / Straight snap options / Snap angle, the default is 90 degrees). The edit frame's starting position is based on the bounding box of the object.Īctually, the new grips show up in the 2D views (Top/Front/Right) for all selected objects, but they will only show up in the 3D view if you have planar objects selected. New stuff:Ä®dit frame: There is now so called object edit frame that shows up around the outside of selected objects which allows you to do scaling, mirroring or rotation very easily without starting up special commands. KGaA, Weinheim.The v2 beta installs into its own folder, it is not a problem to have v1 and any v2 beta installed on the same machine, in fact I recommend that so that you can fall back to v1 if you run into some temporary bad bug in v2. The regulation of the Ï-stacked arrangement of anthracene fluorophores enabled the wide modulation of the fluorescence and a detailed investigation of the relationships between the photophysical properties and the arrangements.Ĭopyright © 2012 WILEY-VCH Verlag GmbH & Co. ![]() This anomalous red shift is probably due to excited oligomer formation in such a lateral 1D arrangement according to the long fluorescence lifetime and little shift in the excitation spectrum. Surprisingly, the brick-like lateral face-to-face arrangement afforded a remarkable red shift of 150 nm to give yellow fluorescence. On the other hand, the 2D end-to-face stacking induced a larger red shift of 60 nm, which is attributed to the excimer fluorescence. The 1D face-to-face zigzag and slipped stacking of the anthracene fluorophores caused a red shift of 30-40 nm in the fluorescence emission with respect to the discrete arrangement, probably owing to ground-state associations. ![]() The monomer arrangement behaved as a dilute solution even in the close-packed solid state to emit deep blue light. Indeed, as the alkyl substituents were lengthened, the organic salts altered their anthracene arrangement to give two-dimensional (2D) edge-to-face and end-to-face herringbone arrangements, one-dimensional (1D) face-to-face zigzag and slipped stacking arrangements, a lateral 1D face-to-face arrangement like part of a brick wall, and a discrete monomer arrangement. Because of the smaller number of hydrogen atoms at the edge positions and the steric effect of the sulfonate groups, 1,5-ADS should prefer face-to-face Ï-stacked arrangements over the usual edge-to-face herringbone arrangement. The arrangements were regulated by using organic salts including anthracene-1,5-disulfonic acid (1,5-ADS) and a variety of aliphatic amines. The construction and precise control of the face-to-face Ï-stacked arrangements of anthracene fluorophores in the crystalline state led to a remarkable red shift in the fluorescence spectrum due to unprecedented excited oligomer formation. ![]()
