With a total of 2 patents, Yang's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
Yang's latest patents include groundbreaking advancements in organic electronic materials. One patent focuses on N-bridged PCBMs, which are synthesized through the cycloaddition of an organic azide to C. These N-bridged PCBMs serve as imino PCBMs, exemplified by an isomeric mixture of [5,6]-open APCBM and [6,6]-closed APCBM. This innovation is particularly relevant for organic field effect transistors and organic photovoltaic devices, where the N-bridged PCBM acts as a fullerene adduct.
Another patent details a method for synthesizing well-defined rod-coil block copolymers consisting of P3HT donor and C-acceptor chromophores (P3HT-b-P(SA)-C). This molecular architecture is designed for use in bulk-heterojunction (BHJ) solar cells. The resulting block copolymer demonstrates reproducible self-assembly into well-defined 'nanofibrils' in thin films. This is the first instance of a block copolymer containing a C-derivative that exhibits an exclusively nanofibrilar structure. The use of this block copolymer as a 'surfactant' significantly enhances device performance by controlling the interface morphology of the P3HT:PCBM donor-acceptor phase domains within the composite.
