Abstract: A photosensitizer and derivative, application thereof. The photosensitizer has the structure of general formula I, wherein X is S or Se, Y is organic or inorganic ion, R1 and R2 are independently selected from H, alkyl, alkoxy, alkyl amido, alkyl azide and the like; R3 is selected from H, alkyl, alkoxy, amino sulfonyl, hydroxyl, carboxyl and the like, and L1 is a linker selected from —(CH2)n1— or —(CH2CH2O)n2—. The derivatives are molecular medicines with drug molecules of anticancer and chemotherapy or tumor targeting function connected to the said photosensitizer. The photosensitizer has excellent near infrared characteristics and low dark toxicity and is used in the field of photodynamic tumor therapy. The introduction of benzophenothiazine or benzophenoselenazine into derivatives with tumor-targeting function could improve the specific uptake of photosensitizer in tumor tissues.

Abstract: The present disclosure provides a lamp and a light source substrate thereof. The lamp includes a receiving body, an assembling stand, a light source substrate, and a lamp head. The receiving body includes a lamp cover and a cover body, the lamp cover is provided with an open end. The assembling stand is inserted into the lamp cover through the open end, and the assembling stand is used for assembling a power module and receiving a fan. The light source substrate is electrically connected to the power module. The light source substrate includes a plurality of end-surface LED substrates and a plurality of side-surface LED substrates. The plurality of end-surface LED substrates and the plurality of side-surface LED substrates are bent and enclosed to form a cylindrical light emitting body and clamp with the assembling stand. The lamp head mates with the cover body.

Abstract: A computer power supply of the present disclosure comprises a housing, a circuit board disposed inside the housing and a fan assembly for dissipating heat from the circuit board, and the fan assembly is disposed obliquely with respect to a surface of the circuit board. With the aforesaid structure, the air produced by the fan assembly of the computer power supply of the present disclosure acts on the circuit board obliquely, and flows out in one direction after dissipating heat from a component that is to be cooled, so the heat dissipation effect is improved.

Abstract: The disclosure provides fluorescence probe compounds of formula I, their preparation methods and applications. These compounds are useful in detecting mercury ions.

Abstract: A fluorescence probe compound, its preparation method and use are provided.
