Abstract
The preparation of particular fluorescent silane dye compositions is disclosed. These silane dye compositions have particular utility as reactants in the preparation of silicone polymeric fluorescent dyes which can be ideally used as chemical indicators in biological sensors.
Claims12
A silane dye composition having the formula ##STR14## wherein Q is a fluorescent dye group;
- Z is a C.sub.1-30 hydrocarbon radical;
- R is a hydrogen atom or a C.sub.1-12 hydrocarbon radical;
- and G is a functional group capable of reacting with a silicone polymer functional group.
A method of preparing a dye-silane composition comprising reacting a substituted polynuclear aromatic hydrocarbon based fluorescent dye of the formula:
- Q-Z-M
- wherein Q is a polynuclear aromatic fluorescent dye moiety, Z is a C.sub.1-30 hydrocarbon radical, and M is a silane reactive substituent selected from the group consisting of halogen, hydroxyl, carboxyl, amine, and amide groups;
- with an unsaturated organo functional silane having the formula:
- ##STR16## wherein X is selected from the group of hydrogen, hydroxyl, and halogen radicals;
- R is a hydrogen atom or a C.sub.1-12 hydrocarbon radical and A is an alkenyl group to form the dye silane of the formula ##STR17##
