Functionalized water soluble macrocyclic complexes of lanthanide, actinide and yttrium ions were obtained by metal templated, Schiff-base, cyclic condensation of: (1) a functionalized 1,2-diaminoethane and a dicarbonyl compound selected from the group consisting of 2,6-dicarbonylpyridine, 2,6-diformylpyridine, 2,5-dicarbonylfuran, 2,5-diformylfuran, 2,5-dicarbonylthiophene and 2,5-diformylthiophene; or (2) 1,2-diaminoethane and a ring-substituted heterocyclic dicarbonyl compound selected from a group consisting of substituted 2,6-dicarbonylpyridine, substituted 2,6-diformylpyridine, substituted 2,5-dicarbonylfuran, substituted 2,5-diformylfuran substituted 2,5-dicarbonylthiophene, and substituted 2,5-diformylthiophene. Coordination complexes thus formed are kinetically stable in dilute aqueous solution. They are further reacted, or coupled, through a substituent on the 1,2-diaminoethane or on the pyridine, furan, or thiophene moieties, to one of the following: proteinaceous materials, polysaccharides, other biologically compatible macromolecules or bridging molecules which can be further reacted or coupled to the above mentioned substrates. These macrocyclic complexes are suitable in the preparation of reporter molecules and for magnetic resonance, radiation imaging and radiation therapy.

摘要:
This invention is directed to a radiation sensitive silver halide emulsion comprising a macroheterocycle having an acid function and to an element containing such emulsion. The macroheterocycle comprises at least two atoms of sulfur or selenium, each of which atoms being separated from one another by a chain of at least two carbon atoms. Such compound acts as a solvent and as a growth modifying agent for silver halide grains. Also described is a process for modifying the growth of silver halide grains.

The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in the case of using an energy storage device at a high temperature and at a high voltage and further capable of inhibiting the gas generation while maintaining a capacity retention rate after storage at a high temperature and at a high voltage and also provides an energy storage device using the same. Disclosed is a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing a carboxylic acid ester compound represented by the following general formula (I). In the formula, each of R 1 and R 2 independently represents a hydrogen atom, a -C(=O)-OR 4 group, or the like, and R 1 and R 2 may be bonded to each other to form a ring structure. R 3 represents a hydrogen atom or the like, and n represents an integer of 1 to 3. When n is 1, then L and R 4 represent an alkyl group having 1 to 6 carbon atoms or the like; and when n is 2 or 3, then L represents an n-valent connecting group, X represents a -C(=O)- group, an -S(=O)-group, an -S(=O) 2 - group, an -S(=O) 2 -R 5 -S(=O) 2 - group or a CR 6 R 7 group, R 5 represents an alkylene group having 1 to 4 carbon atoms, and each of R 6 and R 7 represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms.
