报告摘要：

Incorporation of main group elements into p-conjugated skeletons is a powerful strategy to develop new optoelectronic organic materials with unusual properties. Representative design principles are to make use of an orbital interaction between a p-skeleton and a main-group element moiety. Conformational constraint often plays a crucial role to gain an optimal orbital interaction. In addition, this is also important to gain high chemical and/or photo-stability. Based on this strategy, we have so far synthesized various types of functional p-electron materials. In this lecture, we would like to report recent progress in the development of some new main-group element-containing p-electron materials. In particular, we have recently succeeded in the synthesis of a boron-stabilized triphenylmethyl radical, which shows ambipolar charge carrier transport properties. We have also developed new P=O-containing ladder-type dyes, which can show exceptionally high photostability, and thereby can be employed as promising molecules for super-resolution STED imaging.
