Influences of molecular structures on the spectral properties and photostability of rhodamine dyes

Research Square (Research Square) (2023)

Yudong Liu Fan Chen Liang Sun Zhizhong Zhang Shunzhou Chang

Abstract Although the syntheses and applications of rhodamine dyes have been extensively researched, the photophysical properties and photostability have rarely been studied. In this study, we systematically investigated the photophysical properties and photostability of six rhodamine dyes by the spectrum measurements, photodegradation experiments and theoretical calculations. It was found that the following structural modifications can lead to the redshift of absorption and fluorescence emission spectra: Increasing the alkyls of amino on xanthene; forming rigid ring between the N-linked alkyl and xanthene; esterification of –COOH on benzene ring. The degradation experiments under 525 nm light irradiation indicated that increasing the alkyls of amino on xanthene improves the photostability, fixing the N-linked alkyls on the xanthene ring to form rigid rings would significantly reduce the photostability of rhodamine dyes, and the esterification of –COOH on benzene ring can increase the photostability to some extent. The results of DFT calculations showed that the esterification of − COOH decreases the dihedral angle D 1 and increases D 2 , the variation trend of calculated absorption and emission wavelengths is consistent with the measured results, and the rhoodamine dyes with higher electrophilic index usually have higher photostability.

Facile Tailoring of Anatase TiO₂ Morphology by Use of H₂O₂: From Microflowers with Dominant {101} Facets to Microspheres with Exposed {001} Facets

Industrial & Engineering Chemistry Research (2013)

Taoyun Li Baozhu Tian Jinlong Zhang Rongfang Dong Tingting Wang

A facile hydrothermal route employing H2O2 as structure-directing agent was explored to fabricate anatase microflowers with dominant {101} facets and anatase microspheres with exposed {001} facets. The influence of H2O2 concentration on crystal structure, morphology, and facet composition of TiO2 was investigated in detail. H2O2 plays a crucial role in determining the crystal structure, morphology, and exposed facets of TiO2. The presence of H2O2 favors the formation of anatase phase. When the concentration of H2O2 was in the range 0.7–3.3 M, anatase microflowers with dominant {101} facets were produced. In contrast, when the concentration of H2O2 was higher than 6.6 M, anatase microspheres with exposed {001} facets were formed. A mechanism was proposed to account for the influence of H2O2 on crystal structure and morphology of TiO2. Photocatalytic degradations of rhodamine B and 2,4-dichlorophenol indicated that anatase microspheres with exposed {001} facets showed much higher photocatalytic activity than anatase microflowers with dominant {101} facets.

Au‐Mediated Composite In₂S₃–Au–BiVO₄ with Enhanced Photocatalytic Activity for Organic Pollutant Degradation

ChemistrySelect (2018)

Di Wu Shenyuan Bao Zheng Wang Zhizhong Zhang Baozhu Tian

Abstract A ternary composite photocatalyst In 2 S 3 –Au–BiVO 4 was fabricated by stepwise photo‐reduction and deposition−precipitation methods. It was found that the Au nanoparticles (NPs) were selectively anchored on the {010} facets of decahedral BiVO 4 crystals due to the oriented accumulation of electrons during the photo‐reduction stage. Based on the strong interaction between S−Au, In 2 S 3 was loaded on the surface of Au NPs on BiVO 4 {010} facets. Photocatalytic degradations of organic contaminants Rhodamine B and phenol indicated that In 2 S 3 –Au–BiVO 4 showed evidently improved visible light photocatalytic activity than BiVO 4 , Au–BiVO 4 , and In 2 S 3 –BiVO 4 . On the basis of the photoelectrochemical and photoluminescence (PL) analyses, it can be inferred that the facet hetero‐juction and Au‐mediated composite structures of In 2 S 3 –Au–BiVO 4 can improve the separation efficiency of photo‐generated carriers as well as make the carriers keep higher redox ability. The radical trapping experiments indicated that for In 2 S 3 –Au–BiVO 4 , •OH, h + , and •O 2 − are the main reactive species which take part in the organic contaminant degradation.
