Abstract
The present subject matter relates to a new liquid and solid-state laser system comprising a laser structure and novel 7H-pyrano[2,3-b:4,5-b′]diquinoline derivative compounds as the laser active media; the novel 7H-pyrano[2,3-b:4,5-b′]diquinoline derivative compounds comprising 10-chloro-7H-pyrano[2,3-b:4,5-b′]diquinoline [(Cl-PD)] and 10-methoxy-7H-pyrano[2,3-b:4,5-b′]diquinoline [(MeO-PD)]; and a method of synthesizing the organic 7H-pyrano[2,3-b:4,5-b′]diquinoline derivative compounds used in the laser system.
Claims6
7H-Pyrano[2,3-b:4,5-b′]diquinoline derivative compounds selected from the group consisting of 10-chloro-7H-pyrano[2,3-17:4,5-b′]diquinoline [(Cl-PD)] and 10-methoxy-7H-pyrano[2,3-b:4,5-b′]diquinoline [(MeO-PD)] having the following structures, respectively:
A method of synthesizing organic 7H-pyrano[2,3-b:4,5-b′]diquinoline derivative compounds, the method comprising:
- adding 2-hydroxyquinoline-3-carbaldehyde to propargyl bromide in the presence of sodium hydroxide in n-propanol to produce 2-(prop-2-yn-1-yloxy)quinoline-3-carbaldehyde;
- reacting the 2-(prop-2-yn-1-yloxy)quinoline-3-carbaldehyde with an arylimine in CH2Cl2 to produce a corresponding 2-(prop-2-yn-1-yloxy)quinolin-3-arylimine;
- and
- treating the corresponding 2-(prop-2-yn-1-yloxy)quinolin-3-arylimine with about 20 mol % of boron trifluoride diethyl etherate (BF3O(C2H5)2) in 1,2-dichloroethane to produce the organic 7H-pyrano[2,3-17:4,5-b′]diquinoline derivative compounds.
A liquid and solid-state laser system comprising a laser structure and organic pyranodiquinoline derivatives 10-methoxy-7H-pyrano[2,3-b:4,5-b′]diquinoline [(MeO-PD)] and 10-chloro-7H-pyrano[2,3-b:4,5-b′]diquinoline [(Cl-PD)] employed in an energy transfer mechanism.
