9,10-Bis(p-alkoxystyryl)anthracenes (DSA-pnn) with different length of alkyl chains (n = 4, 8, 16) were synthesized. It was found that they exhibit aggregation-induced emission (AIE) properties and significant fluorescent thermochromism. Besides, the thermochromic behaviours of DSA-pnn show great dependence on the length of alkyl chains.
