We discussed in detail the relationships between the molecular orbital energy, absorption and emission performances and the structures of the four compounds.
In this paper, in order to make a reasonable theoretical explanation for the experimental study, and provide theoretical basis for the further design and synthesis of high performance functional organic light emitting material, by using quantum chemistry calculations, we investigated the structures of the ground and excited states, and the luminescent properties of the four pyridine-containing diacylhydrazones compounds reported in literature [11].
Harmonic frequency analyses were performed at the same levels to confirm that these structures were local minima on the energy surfaces.
In spite of this, but the intramolecular alternate of the single and double bonds is obvious, so the conjugation of the local electronic structure is strong.
Figure.1 The ground state and excited state structures of the four pyridine-containing diacylhydrazones derivatives, 1, 2, 3 and 4.

Activated carbon fibres (ACFs) are porous carbons with a fibre shape and a well-defined porous structure, which are very promising materials because of their high adsorption capacity and rate.
The use of activated carbon fibres has been continuously growing in recent years[2].Porous carbon materials, a material with porous structure and large internal surface area, is commonly used as adsorbent for the removal of organic matter micropollutants (i.e. pesticides, phenols, aromatic hydrocarbons, humic substances, etc.) in drinking water treatment[3-5].

To date, the soft-chemistry of polyoxometalate complexes is being actively studied: new polyoxometalate complexes are being synthesized, and these complexes are being used in various fields [6].
In addition, these systems are of significant interest for fundamental science, since they can be classified as objects of both complex compounds chemistry and colloidal chemistry [8].
The presence of an absorption maximum at a certain wavelength is characteristic of polyoxometalate complexes of a certain structure and form [1-3].

Under acidic condition, the helical structure of collagen was destroyed and pepsin cut collagen into smaller molecules, Ca2+ was combined with citric acid, then calcium citrate was generated [14].
The pepsin could be activated under suitable condition of PEF, because of the structure of enzyme be changed [17].

Simultaneously, dopant engineering has proven to be a valuable route for tailoring the electronic structure and defect landscape of ZnO.
However, achieving homogeneous Y incorporation without secondary phase formation, preserving the aerogel framework, and controlling defect chemistry remain significant challenges [15, 17].
This feature further supports the existence of an interconnected porous structure capable of adsorbing small gas molecules.
The persistence and intensity of this band confirm the hydrophilic surface chemistry and the open porosity of the aerogel frameworks, which readily accommodate water molecules within their nanostructured network.
