To search and development of new latent fingerprint detection agents, the frontier molecular orbital (FMO) interactions between a series of 1-indanone derivatives ( 1 -17), heterocyclic compounds (18 -20) and glycine molecule were studied. The research results are in, and it is suggested that the nucleophilic reaction was more superior due to the orbital controlled reaction by strong interaction between εHOMO energy of glycine and εLUMO energy of 4,5-diazafluorene-9-one (18: IDFO). Therefore, the nucleophilic reaction of 1-indanone derivatives was dependent on the εLUMO energy and positive charge ( δ + ) of carbonyl carbon atom in molecule.
The CoMFA model (A5: predictability, r2 cv.(q 2 )=0.952 and correlation coefficient, r 2 ncv.=0.991) on the εLUMO energy selected at the different alignment conditions, interrelationship, and structural factors contributing to εLUMO energy from the r2 ncv.=0.990 contour were searched. The study results showed that the heterocyclic compounds [IDFO (18) and DFO (19)] were more reactive than 1-indanone derivatives. Also, it is expected that the 4,5-diazafluorene-9-one (IDFO) molecule has the application potentials as latent fingerprint detector.
