A series of copper phthalocyanine derivatives substituted by aliphatic chain were obtained by the reaction of tetra-formyl chloride copper phthalocyanine and aliphatic alcohol such as n-butyl alcohol, n-amyl alcohol, n-hexyl alcohol, n-caprylic alcohol and lauryl alcohol. IR, UV-Vis, elemental analysis and 1H NMR verified the structures and substituting degree. The solubility and the relationship between fluorescence and concentration and substituting group were studied in organic solution. It was confirmed that the solubility in organic solution was improved greatly, the fluorescence did not change in linear according to the concentration and the fluorescence of copper phthalocyanine derivatives substituted by the long alkyl was stronger than that substituted by the relatively short alkyl.

Hybrid excitons formed via resonant hybridization in 2D material heterostructures feature both large optical and electrical dipoles, providing a promising platform for many-body exciton physics and correlated electronic states. However, hybrid excitons at organic-inorganic interface combining the advantages of both Wannier-Mott and Frenkel excitons remain elusive. Here, hybrid excitons are reported in the copper phthalocyanine/molybdenum diselenide (CuPc/MoSe) heterostructure (HS) featuring strong molecular orientation dependence by low-temperature photoluminescence and absorption spectroscopy.

Metal-organic frameworks (MOFs) have been identified as promising electrocatalysts for the oxygen evolution reaction (OER). However, most of the reported MOFs have low electrical conductivity and poor stability, and therefore addressing these problems is crucial for achieving higher electrocatalytic performance. Meanwhile, direct observations of the electrocatalytic behavior, which is of great significance to the understanding of the electrocatalytic mechanism, remain highly challenging.

Article Synopsis
- The study presents an analytic model that improves the understanding of Raman and fluorescence enhancement in molecules situated between two closely spaced gold nanospheres, taking into account higher-order modes along with the traditional dipolar mode.
- The model is validated by gap-dependent tip-enhanced Raman spectroscopy (TERS) experiments, which reveal varying trends of photoluminescence and Raman enhancement as the gap width decreases.
- A red-shift in the background spectra indicates greater coupling between the nanospheres, demonstrating how the model effectively explains the mechanisms at play in the TERS experimental observations.

Article Synopsis
- A 43-year-old man developed itchy nodular lesions on his leg tattoo four weeks after getting it, prompting tests for allergies.
- The tests revealed sensitization to certain inks containing specific dyes, indicating a T-cell hypersensitivity reaction associated with the red pigments.
- While there's debate over the effectiveness of patch testing for tattoo reactions, it can help identify problematic inks and inform future tattoo decisions to avoid similar issues.
