This compound has a certain melting point due to its specific molecular structure. During the heating process, when the temperature rises to a specific value, it will change from a solid state to a liquid state. This temperature is the melting point, which is helpful for its purification and identification.
In terms of solubility, it exhibits certain solubility in some organic solvents, such as common dichloromethane, chloroform, etc. This solubility is related to the polarity of the molecule and the polarity of the solvent, and follows the principle of "similar miscibility". Because its molecular structure contains non-polar parts such as aromatic rings, it has relatively good solubility in non-polar or weakly polar organic solvents.
In terms of optical properties, the compound has certain fluorescence properties. When irradiated by light of a specific wavelength, the electron absorption energy in the molecule transitions to the excited state, and then it will emit fluorescence when it returns to the ground state. This property makes it potentially useful in fields such as fluorescent probes and luminescent materials.
In addition, its stability depends to a certain extent on the environment. Under normal temperature and pressure and general chemical environments, its structure is relatively stable; however, under extreme conditions such as strong acids, strong bases, or high temperatures, the molecular structure may change, causing its physical properties to change.
From the perspective of molecular structure, its multiple ring structures are connected to each other to form a rigid plane. This structure plays a key role in the presentation of its physical properties, such as enhancing the forces between molecules, which in turn affect properties such as melting point and solubility.

To obtain the synthesis method of diethyl-4,11-diazacyclotetradecane-1H-nematic phase [3 ', 4': 6,7] naphthaleno [1,2-b] phenanthrene-3,14 (4H, 12H) -dione, we shall describe it in the ancient method.
First take a suitable starting material, which must contain reactive groups to facilitate the subsequent construction of the skeleton of the target molecule. Aromatic compounds with specific substituents can be selected, and the substituents can react under appropriate conditions to form rings with each other.
In the reaction vessel, add an appropriate amount of catalyst. When this catalyst has high efficiency and specific catalytic properties, it can promote the reaction to proceed in the desired direction. For example, some metal complex catalysts can precisely catalyze the formation of carbon-carbon bonds or carbon-heteroatomic bonds.
Control the reaction temperature and pressure at an appropriate temperature. If the temperature is too high or side reactions occur frequently, if it is too low, the reaction rate will be slow. Generally speaking, the temperature can be maintained within a certain range, such as between [X] and [Y] degrees Celsius, and the pressure is also adjusted to about [Z] atmospheric pressure, so that the reaction system is in a stable state and conducive to the reaction.
During the reaction process, closely monitor the reaction process. TLC, NMR and other analytical methods can be used to know the degree of reaction and the purity of the product in real time. If too many by-products are formed, the reaction conditions should be adjusted in a timely manner, such as changing the amount of catalyst, reaction time or the proportion of reactants.
When the reaction reaches the expected degree, the product should be separated and purified. The target product can be separated from the reaction mixture by column chromatography, recrystallization and other methods to improve its purity to obtain a pure 4,11-diethylamino-4,9-dioxa-1H-nematic phase [3 ', 4': 6,7] naphthalene and [1,2-b] phenanthrene-3,14 (4H, 12H) -dione product.
All the above methods require careful operation by the experimenter and flexible adjustment according to the actual situation to successfully synthesize the target compound.
