HYBRID PHOTOACTIVE MATERIAL, METHOD FOR OBTAINING SAME AND USE OF THE MATERIAL

摘要

The present invention relates to a hybrid photoactive material which includes at least one dye having fluorescent properties and a structure having the general formula (I), which is an aromatic molecule and the resonant forms thereof; where X is selected from CH or N and Y is selected from the group made up of S, O, N, CH and NH; such that when X=CH, Y is selected from S, O, N, CH or NH, and when X=N, then Y=0; n being equal to +1 when Y=O, NH or S and n being equal to 0 when Y=N or CH; R1, R2, R3 and R4 can be mutually identical or different and selected from: H, CH3, CH2CH3 or N(R11) (R12), where R11 and R12 are mutually identical or different and selected from the group made up of: H, CH3 and CH2CH3; said dye being contained and encapsulated in a crystalline porous material with magnesioaluminophosphate (MgAPO) composition, characterised by having pores with a first diameter in the interval of 4 to 7 Å, both limits included, and a second diameter in the interval of 4 to 7.5 Å, both limits included, which has a one-way system of channels defined by rings of ten to twelve atoms of Al and P with tetrahedral coordination. The invention further relates to a method for preparing the previously defined hybrid material, and to the uses of said hybrid material.
