## Abstract Resorting to β€˜click chemistry’, four photochromic dendrimers, A‐Tri‐SP, B‐Tri‐SP, C‐Tri‐SP, and D‐Hex‐SP, have been synthesized facilely in sound yields of 85, 88, 94, and 80%, respectively. These dendrimers have been obtained by the straightforward coupling of azido‐attached photochrom
