Identification and Quantification of Riboflavin in Vitamine Tablets by
Total Luminescnece Spectroscopy.
Romald E. Utrecht
J. Chem. Educ. 1993, 70, 673.
Riboflavin
is vitamin
B2.
Riboflavin is determined via fluorescence
spectroscopy. The fluorescence is strongest at 530 nm when
excited at 470 nm. Make sure you undertand the excitation/emission plots
in Figures 1 and 2.

Building Block Synthesis of Porphyrine Light-Harvesting Arrays.
Johnson, T. E.; Lindsey, J. S.
J. Am. Chem. Soc. 1993, 115, 7519-7520.

Photosynthetic organisms employ light-harvesting complexes to capture
dilute sunlight and funnel energy to the reaction centers. Understanding
light harvesting phenomena at the molecular level is a major objective of
photosynthesis research and might also provide the foundation for the
design of synthetic molecular devices.

New Developments in the Photonic Applications of Conjugated Polymers.
F. Hide, M. A. Diaz-Garcia, B. J. Schwartz, and A. J. Heeger
Acc. Chem. Res. 1997, 30, 430-436.
An excellent review of absorption and photoluminescence spectra of organic
polymers. The paper describes how these materials can be used in organic
lasers.
Calix[4]arene Podands and Barrelands Incorporating 2,2'-Bipyridine
Moieties and Their Lanthanide Complexes: Luminescence Properties.
G. Ulrich, R. Ziessel, I. Manet, M. Guardigli, N. Sabbatini, F.
Fraternali, G. Wipff
Chem. Eur. J. 1997, 3, 18151822.
Demonstrates a light conversion process consisting of light absorption
(A), ligand to metal energy transfer (ET), and metal luminescence (E).
The ligands are bipyridines and the metal is a rare earth metal (Eu or Tb
trication). Calixarenes are used to hold the ligands in place. Take a
look at Figures 3 and 4.
