METHOD AND COMPOUND

摘要

A method of forming a layer of an electronic device, for example an organic light-emitting device, the method comprising the step of depositing a precursor layer comprising a compound of formula (I) and reacting the compound of formula (I) in a ring-opening addition reaction:;Core-(Reactive Group)n  (I);wherein Core is a non-polymeric core group; and each Reactive Group, which may be the same or different in each occurrence, is a group of formula (II):;;wherein Sp1 independently in each occurrence represents a spacer group; w independently in each occurrence is 0 or 1; Ar in each occurrence independently represents an aryl or heteroaryl group; R1 in each occurrence independently represents H or a substituent, with the proviso that at least one R1 is a substituent; n is at least 1; and * is a point of attachment of the group of formula (II) to the Core; and wherein the compound of formula (I) reacts with itself or with a non-polymeric co-reactant.

1. A method of forming a layer of an electronic device, the method comprising the step of depositing a precursor layer comprising a compound of formula (I) and reacting the compound of formula (I) in a ring-opening addition reaction:
Core-(Reactive Group)n  (I) wherein Core is a non-polymeric core group; and each Reactive Group, which may be the same or different in each occurrence, is a group of formula (II): wherein: Sp1 independently in each occurrence represents a spacer group; w independently in each occurrence is 0 or 1; Ar in each occurrence independently represents an aryl or heteroaryl group that is unsubstituted or substituted with one or more substituents; R1 in each occurrence independently represents H or a substituent, with the proviso that at least one R1 is a substituent; n is at least 1; and * is a point of attachment of the group of formula (II) to the Core; and wherein the compound of formula (I) reacts with itself or with a non-polymeric co-reactant.
