M. Khalid et al., SYNTHESIS AND PROPERTIES OF DYE-CONTAININ G POLYAMINO ACID FOR THE LANGMUIR-BLODGETT-FILM DEPOSITION, Vysokomolekularnye soedinenia. Seria A, 36(3), 1994, pp. 515-518
Pathways are considered for the synthesis of polyglutamic acid bonded
to various dyes, including 7-amino- and 7-hydroxycumarines, safranine
T, and carbocyanines. The highest content of dyes is achieved upon the
immobilization of carbocyanines. All the synthesized compounds are ca
pable of forming colored monomolecular Langmuir-Blodgett films.
