The present disclosure is directed to methods of making a polymer, including exposing a reaction mixture including a strained cyclic unsaturated monomer and an organic initiator to a stimulus to provide an activated organic initiator, whereby the activated organic initiator is effective to polymerize the strained cyclic unsaturated monomer via a 4-membered carbocyclic intermediate to provide a polymer having constitutional units derived from the strained cyclic unsaturated monomer.

PDI derivatives useful as opto-electronically active materials or for the synthesis of such materials. Certain compounds herein function as efficient electron acceptors and are useful as electron active components of electronic devices.

The present disclosure provides a polythiophene derivative, a composite and a manufacture method thereof. The composite is used for a substrate of Quantum dots and Organic Light Emitting Diode, and includes the polythiophene derivative and adulterating agents. A structural formula of the polythiophene derivative is the formula I below, wherein R is selected from one of a straight-chain alkane, a branched-chain alkane or a branched aromatic hydrocarbon, and wherein n represents the number of repeat units and may be a natural number within from 1 to 5000. Through the mean above, the present disclosure mitigates color mixing from confusion in QDs or luminescent materials of different colors and raises the color purity.
