Poly(arylene-ethynylene)s containing dithia[3.3]metaphane

This account provides a summary of our research on poly(arylene-ethynylene)s (PAEs) containing dithia[3.3]metaphane such as dithia[3.3]metacyclophane and dithia[3.3](2,6)pyridinophane. Synthetic procedures, characterizations, optical properties, and their potential applications in a recyclable catalyst and metal sensor will be presented.
