Abstract

A new main-chain NLO hyperbranched polymer (P1) was first prepared through a simple synthetic route, which demonstrated much better NLO properties (d33 value up to 143.8 pm/V) than its corresponding linear analogue (P2), since the three-dimensional spatial isolation from the highly branched structure could greatly enhance the poling efficiency.
