      Environment on Photophysical Properties.

AB  - A new 2,7,10,15-tetraethynyldibenzo[g,p]chrysene ligand (1) and two tetranuclear 
      gold(I) derivatives containing PPh(3) (3) and PMe(3) (4) phosphines were 
      synthesized and characterized by (1)H and (31)P NMR, IR spectroscopy, and 
      high-resolution mass spectrometry. The compounds were studied in order to analyze 
      the effect of the introduction of gold(I) on the supramolecular aggregation and 
      photophysical properties. Absorption and emission spectra displayed broad bands 
      due to the establishment of pi pi interactions as an indication of intermolecular 
      contacts and the formation of aggregates. A decrease of the recorded quantum 
      yield (QY) of the gold(I) derivatives was observed compared to the uncomplexed 
      ligand. The introduction of the complexes into poly methyl methacrylate (PMMA) 
      and Zeonex 480R matrixes was analyzed, and an increase of the measured QY of 4 in 
      Zeonex was observed. No phosphorescent emission was detected.
