dc.description.abstract | The opto-electronic properties of small-molecules and functional dyes usually differ when incorporated
into solid matrices with respect to their isolated form due to an aggregation phenomenon that alters
their optical and fluorescent properties. These spectroscopic modifications are studied in the framework
of the exciton theory of aggregates, which has been extensively applied in the literature for the study of
molecular aggregates of the same type of molecules (homoaggregation). Despite the demonstrated
potential of the control of the heteroaggregation process (aggregation of different types of molecules),
most of the reported works are devoted to intramolecular aggregates, complex molecules formed by
several chromophores attached by organic linkers. The intramolecular aggregates are specifically
designed to hold a certain molecular structure that, on the basis of the exciton theory, modifies their
optical and fluorescent properties with respect to the isolated chromophores that form the molecule.
The present article describes in detail the incorporation of Rhodamine 6G (Rh6G) and 800 (Rh800) into
polymeric matrices of poly-(methyl methacrylate), PMMA. The simultaneous incorporation of both dyes
results in an enhanced fluorescent emission in the near-infrared (NIR), originating from the formation of
ground-state Rh6G–Rh800 intermolecular heteroaggregates. The systematic control of the concentration
of both rhodamines provides a model system for the elucidation of the heteroaggregate formation. The
efficient energy transfer between Rh6G and Rh800 molecules can be used as wavelength shifters to
convert effectively the light from visible to NIR, a very convenient wavelength range for many practical
applications which make use of inexpensive commercial detectors and systems. | es |
