1-2 light emissionA typical fluorescent dye molecules dispersed molecules such as dilute solutions, States that high fromWhereas the optical efficiency, in high concentration solution and condensed phase molecular aggregate (meetings)System, by concentration quenching quenching emission to be known. In recent years, personified.AIE phenomenon to increase intensity in Shu State (Induced AggregationEmission) 23-26 has been reported. For example, as shown in Figure 1 - cyano and BiffWith ENR 3-substituted alkenes, in dilute aqueous solutions by molecular rotation in 無輻Facial not place emitting inactivation. And, on the other hand, the cohesion molecules of biphenylHeat inactivation is suppressed for the child in the rotation is limited, exhibit strong emission. This light emissionEfficiency is reported can range from 700 times compared to dilute 27. In addition,In the aggregation State observed the interactions between metal complexes, AIE propertiesMany examples are reported. Is shown in Figure 1-2 Gold, photoluminescence quantum yield in aqueous solutionTo only 0.004 and very weak emission solution around in the solid state, regardless ofDue to the intensity in emission, this luminous works between the gold atoms interaction 200 times28 have been reported.

1-2 emitting
common fluorophores such as dilute solutions, higher originating in a state in which molecules are dispersed

to the system So it is known that light emission is quenched by concentration quenching. The In recent years, the co
is a phenomenon in which light emission intensity is enhanced in collecting state AIE (Aggregation Induced
Emission) have been reported 23-26. For example, a cyano group and Biff, as shown in Figure 1-1
tri-substituted alkenes having ~Eniru group, no congestion by the rotating molecules in dilute solution
does not exhibit Ishitsukatsu occurs emission. On the other hand, when the molecules are aggregated, minute biphenyl group
for the child in the rotation is restricted is heat-inactivated suppression I exhibit strong emission. In this case light emission
efficiency has been reported that extends to 700 times as compared with a dilute solution 27. In addition to this,
the AIE properties in the metal complex intermetallic interactions are observed in the aggregated state
example shown have been reported. Gold complex as shown in Figure 1-2, the light-emitting quantum yield in solution
despite the not shown only very weak emission and 0.004, in the solid state about in the solution
shows the emission at 200 times the strength, the light-emitting due to the interaction acting between the gold atoms
28 have been reported.

， fluorescent dye molecules emit light at a generally like to dilute solution ， molecules in high efficiency at the light from the state in which the dispersed phase of aggregation and molecular aggregation in high concentration solution ， (meeting) in the system is known by. Concentration quenching luminescence quenching. In recent years ， AIE phenomenon in which light emission intensities in enhanced coagulation at the state of Aggregation Induced at Emission reported that 23 - 26. For example, the ， trisubstituted alkenes with ェニル biff group at the base and ， as shown in Fig. 1No fire without light emission caused by radial to deactivation of the internal rotation in dilute solution. On the other hand ， molecular aggregation and ， for biphenyl group limited minutes in a rotating element exhibiting strong emission from thermal inactivation. It is reported that the light emitting efficiency at this time to 700 times compared with a dilute solution. In metal complexes in addition to mmeans aggregation state is observed in the interaction between metal and has been reported in many cases showing at the AIE characteristics. ， gold complexes in quantum yield of light emission in solutionThough not shown in ， only very weak light emission and 0.004 ， in solid solution state and luminescence intensity of about 200 times has reported that due to a light emission in the mutual action between the gold atom interaction.
