A set of ladder‐type quaterphenyls with an incremental number of spiro‐bifluorene units in the bridge positions as well as an in‐plane bent quaterphenyl carrying all bridges on one and the same side of the ribbon are synthesized and characterized. While spiro‐bifluorene substituents lead to bathochromically shifted maxima in the UV–vis absorption spectra, this effect can be compensated by in‐plane bending. The influence of different deposition techniques on the solid state structure is analyzed by X‐ray diffraction of single crystals obtained by crystallization from solution as well as sublimation. An increasing number of spiro‐bifluorene substituents are found to aid thin‐film formation.

螺旋桥阶梯型低聚对苯亚胺：精细调节的固态结构和光学性质

合成并表征了一组在桥的位置具有递增数目的螺二芴单元的梯型四元苯基以及在带的同一侧上带有所有桥的平面内弯曲四元苯基。尽管螺二芴取代基会导致紫外可见吸收光谱中的红移，但该效应可以通过面内弯曲来补偿。通过从溶液中结晶以及升华获得的单晶的X射线衍射分析了不同沉积技术对固态结构的影响。发现越来越多的螺二芴取代基有助于薄膜形成。
