ABSTRACT:
The present invention provides a dye loaded zeolite material comprising: a) at least one zeolite crystal having straight through uniform channels each having a channel axis parallel to, and a channel width transverse to, a c-axis of crystal unit cells; b) closure molecules having an elongated shape and consisting of a head moiety and a tail moiety, the tail moiety having a longitudinal extension of more than a dimension of the crystal unit cells along the c-axis and the head moiety having a lateral extension that is larger than said channel width and will prevent said head moiety from penetrating into a channel; c) a channel being terminated, in generally plug-like manner, at least at one end thereof located at a surface of the zeolite crystal by a closure molecule hose tail moiety penetrates into said channel and whose head moiety substantially occludes said channel end while projecting over said surface; and d) an essentially linear arrangement of luminescent dye molecules enclosed within a terminated channel adjacent to at least one closure molecule and exhibiting properties related to supramolecular organization.
