Semiconductor nanocrystals

摘要

Modifying a semiconductor nanocrystal surface comprises: providing an organic coating layer of semiconductor nanocrystal by at least one reactive group G1 using a cycloaddition reaction of click chemistry type on the external nanocrystal surface, and mixing the nanocrystal with an additional material provided by at least one complementary group G2 of the group G1 with respect to the click chemistry reaction, in the conditions favorable to the interaction of the groups G1 and G2.

An INDEPENDENT CLAIM is included for a surface modified semi-conductive nanocrystal obtained by the process.
