Title: J Lester Matthews: Innovator in Naphthalimide Dyes
Introduction
J Lester Matthews is a prominent inventor based in Dallas, TX (US). He has made significant contributions to the field of chemistry, particularly in the development of innovative dyes. With a total of 15 patents to his name, Matthews has established himself as a key figure in his area of expertise.
Latest Patents
One of his latest patents is focused on dimeric non-azo naphthalimides and their various applications. This class of predominantly hydrophilic 1,8-naphthalimide dyes contains at least two 1,8-naphthalimide ring systems, which are joined by a spacer moiety. Each ring system features a ring nitrogen atom and an amino nitrogen atom at the 4 position, carrying a hydrogen. The remaining unsatisfied valences of the ring nitrogen or amino nitrogen atoms are occupied by one or more alkyl substituents. Notably, these compounds are free of azo substituents and nucleofuges. Upon activation by an agent in an oxygen-independent environment, they generate activated species capable of causing structural changes in lipids and associated proteins, leading to polymerization and crosslinking.
