Abstract
An emissive Pt(II) coordination polymer (TBP) was synthesized by assembling a benzothiadiazole-based Pt(II) acceptor (A) with a tetraphenylethene (TPE) containing donor (L). Multiple benzothiadiazole units in the polymeric array of the TBP rendered it with reactive oxygen species generation ability. TBP was found to be an excellent photocatalyst for oxidative coupling of benzylamine under visible light with full conversion within 2 hours at room temperature and reusability for multiple cycles. Such photocatalytic efficiency under ambient conditions, reusability of the catalyst, and easy separation of the product are noteworthy.
