将取代基引入3，3-二芳基-3 H-萘并[2，1-B]吡喃的3-（4-吡咯烷基苯基）环的空间要求高的2-位，导致产生额外的短波长吸收带，导致有机光致变色物，其表现为橙子和红色的暗色调。(c)2005爱思唯尔有限公司保留所有权利。
Introduction of a substituent into a sterically demanding 2-position of a 3-(4-pyrrolidinophenyl) ring of a 3,3-diaryl-3H-naphtho[2,1-b]pyran results in the generation of an additional short wavelength absorption band leading to organic photochromes that appear as dull shades of orange and red.
