5-Methyl-2-[(2-nitrophenyl)amino]-3-thiophenecarbonitrile is a crystalline compound rich in conformational polymorphs largely owing to the flexible torsion angle that leads to distinct colors, earning it the moniker ROY (Red-Orange-Yellow). Guanidinium organosulfonate hydrogen-bonded frameworks form six crystalline inclusion compounds with ROY, described here, in which the framework limits conformational twisting out of plane. Three of the six inclusion compounds enforce greater planarity and π-conjugation than any of nine ROY polymorphs that have been characterized by single crystal X-ray diffraction.

ROY局限于氢键构架：发色团的强制构象

5-甲基-2-[（（2-硝基苯基）氨基] -3-噻吩甲腈是一种富含构象多晶型物的结晶化合物，主要是由于其挠曲的扭转角导致了不同的颜色，因此获得了绰号ROY（红橙色橙））。胍基有机磺酸氢键结合的骨架与ROY形成六个结晶夹杂物，在此描述，其中骨架限制构象扭曲平面外。六个夹杂物化合物中的三个比通过单晶X射线衍射表征的九个ROY多晶型物中的任何一个具有更高的平面度和π共轭。
