TI  - New hybrid films based on cellulose and hydroxygallium phthalocyanine. Synergetic 
      effects in the structure and properties.
PG  - 3712-22
AB  - Hydroxygallium phthalocyanine (HOGaPc) and cellulose (from a trimethylsilyl 
      derivative) have been used as native elements for the preparation of a novel 
      family of hybrid films. By spin-coating, both components allow the building of 
      films with different configurations on various substrates in a controlled way. 
      The particularities of these hybrid films have been characterized by a range of 
      techniques such as Fourier transform infrared spectroscopy (FTIRS) in attenuated 
      total reflection using multiple internal reflections (ATR/MIR), absorption 
      ultraviolet and visible spectroscopy (UV-vis), X-ray photoelectron spectroscopy 
      (XPS), atomic force microscopy (AFM), and surface potential measurements using 
      the Kelvin-Zisman vibrating capacitor probe (KP). This enabled determination of 
      the influence of cellulose on the arrangement of HOGaPc and, consequently, 
      control of the relation between the structure and the properties of the films. 
      Finally, gas sensor tests were performed to check the potentialities of these 
      hybrid films. In particular, the synergetic behavior between the film-forming 
      materials allows a fast and sensible change in surface potential after cyclic 
      exposures to ozone (O3, 100 ppb) and nitrogen. Overall, we present the advantages 
      of combining phthalocyanine with cellulose in enhancing the properties of the 
      final product. Introduction of cellulose as a host material opens up a new area 
      of hybrid films.
