Abstract

 INTRODUCTION: ORGANIC AND ORGANOMETALLIC DYES WITH LARGE TWO PHOTON ABSORPTION (TPA) CROSS SECTION ARE IN DEMAND FOR SEVERAL APPLICATIONS RANGING FROM IN VIVO BIO-IMAGING TO NANOFABRICATION AND FOR THE LOCALIZED RELEASE OF BIO-ACTIVE SPECIES. [1] WE PRESENT A JOINT THEORETICAL AND EXPERIMENTAL WORK AIMED TO UNDERSTAND THE SPECTROSCOPIC BEHAVIOR OF MULTIPOLAR DYES OF INTEREST FOR NONLINEAR OPTICS (NLO) APPLICATIONS. HENCE TO GAIN A UNIFIED DESCRIPTION, WE HAVE DEVELOPED A MODEL BASED ON A FOUR-STATE DESCRIPTION OF THE CHARGE-TRANSFER PROCESSES CHARACTERIZING THE LOW-ENERGY PHYSICS OF THESE SYSTEMS.THE MODEL ACCOUNTS FOR MOLECULAR VIBRATIONS AND POLAR SOLVATION AND REPRODUCES THE ANOMALOUS EVOLUTION WITH SOLVENT POLARITY OF EXPERIMENTAL ABSORPTION BAND SHAPES. ALSO FLUORESCENCE AND EXCITEDSTATE ABSORPTION SPECTRA ARE WELL-DESCRIBED WITHIN THE SAME MODEL. THE PROPOSED MODEL PROVIDES USEFUL GUIDELINES FOR THE SYNTHESIS OF DYES FOR TPA APPLICATION.
