First Time

The HeI/HeII photoelectron spectra of substituted fluorenes (2-aminofluorene, 2,7-dibromofluorene, 2-acetylfluorene, and 9-trimethylsilylfluorene) are reported for the first time. We have observed significant changes in the π-electronic structure of the title molecules on substitution at 2-, 7-, and 9-positions and interpreted them within the theoretical framework of resonance and inductive effects. The substituents attached to fluorene at these positions govern the photophysical behaviour and properties of polymetallaynes that contain the fluorene moiety. The mediated properties include the size of the polymer bandgap, various non-linear optical properties, and the intensity and lifetime of luminescence processes. Our spectral results provide some detailed explanations of substituent influences in the form of, for example, orbital ionization energies, which can be further related to charge-transfer processes present in these metallo-organic polymers.

Molecular Picture

<span>Inorganic semiconductor devices such as transistors have been instrumental in shaping the development of our society of information and communication. Recently, the electronics and photonics technologies have opened their materials base to organics, in particular p-conjugated oligomers and polymers. The goal with organics-based devices is not necessarily to attain or exceed the level of performance of inorganic semiconductor technologies...</span>
